Table 4-21 HTTP Cache Freshness Fields
Field Description
Enable When checked, HTTP cache freshness is enabled.
Object Age Multiplier The age multiplier value (as a percentage) enables the SE to guess the life
of an object by multiplying the time since the object was last modified by a
percentage to obtain an approximate expiration date. After this date, the
object is considered stale, and subsequent results cause a fresh retrieval by
the SE. The range is from 0 to 100. The default value is 30.
Max TTL Scale The scale (seconds, hours, minutes, or days) to use for the Max Object TTL.
The time-to-live (TTL) sets a ceiling on estimated expiration dates. If an
object has an explicit expiration date, this takes precedence over the
configured TTL.
